MI High - Series 3 - Fit to Wurst

The children of St Hope's are getting fatter and fatter. They are addicted to wursts. The spies must stop this addiction and find out who is behind it. Jed Black, MI9 Head of Training, has come to St Hope's. His aim is to get the spies fit, really fit. While the spies are doing thousands of press-ups in the gym, something rather sinister is going on in the school. Luvabitz arrives in his wurst van. He hands out free, greasy, delicious wursts. The kids and Frank are addicted. They can't get enough of them and as a result are getting fatter and fatter. Back in the gym, the spies have been tied up and Jed has set them the task of breaking free within an hour. Once they untangle themselves, they quickly realise that this was a ploy to ensnare them. Jed is not who he seems. Something is going on and they can't get hold of Frank. When they finally get to HQ, Frank has ballooned to three times his normal size and is still devouring his beloved wurst! The team quickly realise that they're under attack. The team must discover who is behind this before all the children in the land become the size of whales!
